ratelena [41]
1. 7 = 4s + 19
7 - 19 = 4s
-12 = 4s
s = -3

2. x/4 + 8 = 16
x + (8 × 4) = 16 × 4

Simplify (3x2 − 2) + (5x2 + 5x − 1). (2 points)
olga55 [171]

Answer:

D

Step-by-step explanation:

well the anser has to equal 9 if you solved the question correctly BUT the other questions have to equal 9 so the first one is like this

(3*2-2)+(5*2+5*-1)



= (6-2)+(5*2+5*-1)



= (4)+(5*2+5*-1)



= 4+(5*2+5*-1)



= 4+(10+5*-1)



= 4+(10+-5)



= 4+(10-5)



= 4+(5)



= 4+5



= 9

Now the answers A is not it because

8*2+5*-3



= 16+5*-3



= 16+-15



= 16-15



= 1

B isnt it because

8*2+5*-1



= 16+5*-1



= 16+-5



= 16-5



= 11

And C isnt it because

2*2+5*-3



= 4+5*-3



= 4+-15



= 4-15



= -11

So that leaves D and this is how it is correct

= 8*2+7*-1



= 16+7*-1



= 16+-7



= 16-7



= 9


Hope this helps! Sorry I took so long
